Couple of days ago I bought a Yong nuo rf 602 wireless trigger for external flashes.
I was kinda skeptical about Chinese made triggers but for 30 USD you can't go wrong with this one.
I had a cheapo trigger that I was using years ago. It was like 15 bucks from ebay. Worked like a charm the first few weeks until I replaced the batteries. After that it was basically failing after 2 shots or so.
I then bought a Microsync from Tamrac
It worked perfectly for the higher end flashes. I was so fond of it I even brought it to our work. I tried it on our Calumet lights at work and it never failed me...not even once.
I then tried it on some of my cheap Chinese made lights...that is when I realized that the Microscync does not really work on them that good. It really didn't work at all! I was using those cheap sl-150's. My 15 dollar trigger works on them like a charm...but not the Microsync.
I really didn't care at all, till I was planning to buy a secondary receiver. The receivers were around 80-100 bucks online. Pretty expensive so I opted for a cheaper more reliable alternative. I didn't wanna spend 400 bucks on a set of pocket wizards so I browsed online and I found the Yong nuo rf 602.
The first time I opened the box, I was very impressed. Build quality was far from the usual disposable builds of other Chinese made triggers. It was pretty nice. The buttons were snappy the battery compartment was decent and the receiver can also be used for speedlites. So I put it on my Sigma flash and it works! It even wakes the flash when it's in sleep mode. The transmitter sits on the camera body nicely. The best thing about it was that it even works on any external flashes, even the cheap ones!
So I decided to put it in my Sigma flash, put the flash on a stand and go out to shoot! It was night time so it was pretty dark outside. I took a shoot of this spider and my flash worked perfectly!
So the Microsync goes to ebay so I can buy a secondary receiver for my rf 602.
